摘要
黑龙江省高速公路监控系统摄像机沿道路呈线性分布,采用EPON无源光网络技术对外场监控摄像机进行组网并构建前端接入网络。EPON的组网方式,可以极大的节省主干线路光纤资源,且每个监控点到交换机都为独享带宽。
Heilongjiang Provincial expressway monitoring system camera along the road is in a linear distribution. It adopts EPON passive optical network technology, constructs the network of field surveillance cameras and the front access network. EPON networking mode can greatly save the truck fiber resources, and each monitoring point to switch to enjoy bandwidth alone.
